This is an example (the scrollio picture viewer that I convert to take dib) with new control LargeBar
Now I can open a 20 Mpixel photo and select zoom 2000%.
The code of scrollbar is small. Return from vertical to horizontal bar automatic (we can change manual if we want). No flickering and has tab stop so we can use keyboard, arrows and pageup and pagedown,
For history the original scrollio from dilettante is here http://www.vbforums.com/showthread.p...er-UserControl
New version of scrollio, a dilettante's simple picture viewer. But now can open jpg and rotate according the exif property.
ScrollBar updated to work perfect and with a good looking design. Now we can export and import from clipboard as DIB (without loosing dpi). Also i have a menu to see someone how the image can be with 300 dpi as 1:1 ratio (1 pixel of image for 1 pixel of screen). Also I put two pictureboxes, one grab and fit the scrollio image (the part we saw) and the other is using to print two axes on a small picture of the dib inside scrollio, marking the movement of pointer above viewer. As we move on the picture, or the picture, we see the exact coordinates in pixels, in any size and any scrolling position (pure mathematics).
Also I put a slider as a scale controller...and you can see how fast dib works. Also I put a drawing over the displayed image as a target...to demonstrate how we can print on the picturebox (the displayed part of scrollio).
scrollio.image is the picturebox
scrollio,dib is the cDibSection
When the image was ending from the painting send an event PaintEnd so we can draw on image or we can grab it
Also there is a new event, a mousemove, at the "paper" the picturebox inside scrollio, that fires in any state of button, and before processed in the command for hand scrolling. This is needed for taking the current x and y, when no action for redrawing needed..So with that I insert action to have a feedback;
